Description

[Detailed Description of the Invention] [Industrial Application Field] When changing parameter settings using an operator, the present invention divides the setting values into groups and changes them at normal speed, with a longer time in between the groups. This article relates to a parameter setting device that provides a gap. [Prior Art] This device is capable of setting a large number of parameters for an electronic musical instrument, and when a performer sequentially operates the controls to set a desired value, he or she usually operates according to a predetermined sequence. It changes in the + or 1 direction depending on the child. For example, if the device has two types of controls, one for changing +1 and one for changing -l, and can be set to up to 100 types, the settings can be changed in sequence by holding down the +1 control. ．． In recent electronic musical instruments, the setting types are divided into groups such as piano group and organ group for tone settings, and within each group, such as Viano 1, Piano 2, Electronic Piano L, Electronic Viano 2, etc. It is possible to set multiple types of similar tones, and they are divided by numbers. For example, the piano group is numbers 11 to 20.
until the organ group number 21 to 25-
It looks like this. In addition, there is also a device that has new humidity controls of +10 and -10 in addition to +1 and -1 as operators. In that case, for example, from setting number 3 to 75
When changing to the number setting, instead of operating +1 72 times, you only need to operate +10 seven times and +1 twice, which greatly improves operability.

Furthermore, in many musical instruments, when the set upper limit value is reached, the setting is shifted to the other limit value at the next moment.

For example, when you reach number 100 from a small value, you can move to number O, or when you reach number O from a large value, you can move to number 100. When changing settings, you can change settings at the upper or lower limit value. is repeated endlessly.

[Problem A to be Solved by the Invention] Even if the limit value is reached by operating the operator by ``mmL'', it will continue to change as usual after that, so when changing the setting to a position close to the limit value in conventional devices, , sometimes the desired setting value was exceeded.For example, when changing from number 85 to number 3,
If you continue to operate the +1 control, it will change from number 85 to number 3 after passing number 100, so I plan to stop operating it after number 100, and it will immediately change to number 4 and 5. This is because the change tempo of the timbre setting value based on the continuous operation of the operator and the grouping of the setting value are processed without being correlated with each other.

SUMMARY OF THE INVENTION An object of the present invention is to provide a parameter setting device that improves the above-mentioned drawbacks and allows the setting values to be changed slowly between groups when changing the setting values of grouped parameters by continuous operation of the operator. It is in.

[Means for Solving the Problem] The present invention provides a parameter setting device for an electronic musical instrument that sequentially changes parameters set by the parameter setting device at a predetermined tempo by continuously operating a parameter setting operator. The invention has the following configuration. In other words, multiple parameters that can be set are further divided into groups, and when the setting change reaches the end of a certain group by operating the controller, the setting change to the next group is performed at the same time as the change time to the adjacent setting value within the group. This should be executed after a longer period of time has elapsed.

[Function] When operating the controls to set parameters such as timbre and change the setting values, the parameters to be set are divided into groups in the data storage device in advance, and the upper limit and Stores data indicating that it is the lower limit. Next, when the controller is pressed and held continuously, the parameter setting device changes the changed setting value at a predetermined tempo to the predetermined value, but in the meantime, the changed setting value is Determine whether it is the upper or lower limit value, and if so, change the next parameter setting value by changing the tempo clock by 2 to 3 seconds.
Count an extra number and then execute.

[Embodiment] FIG. 1 shows an overall block diagram of an electronic musical instrument including an operation panel 1, as an embodiment of the present invention, in a case where tone settings are changed using an operator. In FIG. 1, 1 is an operation panel, 2-1.2-2 is an operator for changing set values in increments of +1 and -1, and 3-1. 3-2 indicates an operator that changes the value by +10 and -10. 4-1.4-2 are switches for selecting and specifying the tone series to be set, for example, melody 1,
Melody 2 is selected, and 5 indicates a display window that displays setting value changes. Further, 9 is a keyboard, 10 is a central processing unit, 13 is a musical tone forming circuit, and 15 is a tempo timer, which sends a request signal for switching the displayed tone (parameter) and a request signal for selecting the display. is output to the central processing unit. 16 is a program and data memory, 17 is a data and work RAM, 19 is a D/A converter, 20 is an amplifier, and 21 is a speaker. The program and data memory 16 contains programs for operating the central processing unit. Waveform data for musical tones, numbers that group tone settings,
Stores codes that specify that this is the first or last setting number within a group. The data and work RAM 17 also includes a work register for calculating a set tone number and displaying it on the display window, and a status register for indicating the status of each operator. It has a buffer that stores the timbre number for each timbre series and a counter that sets the switching time.

In the electronic musical instrument shown in FIG. 1, when the operators 2, 3.4 are operated, the central processing unit 10 starts operating according to the operation flowchart shown in FIG. That is, the central processing unit constantly scans and monitors the states of the controls on the control panel 1, and when it determines that an on-event has occurred for the controls in step ■, the central processing unit performs the operations in steps ■ and ■. Determine whether the child is a series selection side or a setting number operator. If you are on the series selection side, step ■
Proceed to , and perform series selection processing. Next, the process returns to the panel scan process and waits for the setting number operator to be operated. When the setting number operator is operated, the process proceeds to step (2) and sets the press and hold flag; otherwise, the process proceeds to step (2) to clear the press and hold flag. After the processing in step (2), the process proceeds to step (2) and the tone color number is set in the RAM 17.

Further, in step (2), a value obtained by counting the number of tempo clocks since the start of operation of the operator is set in the RAM 17. Then, in step 2, the old cent value and the new set value are added (or subtracted when operating the -1 operator).
It is determined whether the resulting value is the same as the limit value of the group number value in step [phase]. If they are the same, they are saved in a register in the RAM 17 in step 0. If they are not the same, save that fact in the same register and proceed to step (■). If they are the same, in step 0, the tone number is displayed after the tempo timer clock has elapsed, for example, by three times. Then, in step [phase], a display number is set and a signal to the musical tone forming circuit 13 is prepared. If it is not the limit value within the group, after step @, the process proceeds to step (2) and the tone color number is displayed according to the normal clock from the tempo timer. Next, in step [phase], a display number is set and the tone forming circuit l3
Prepare a signal for. No signal is sent out yet.

Note that if the setting number operator is not an on event, step O. [Phase] displays the previous tone number.

After this, when the desired set value is reached, if you check the display and stop operating the controls, the tone selection will be changed after a short period of time.
Sent on 3rd.

Setting of such parameters is not limited to timbre, and other types of parameters can be set and changed in the same way.

[Effects of the Invention] Thus, according to the present invention, when setting and changing parameters by grouping them, even if the change operator is continuously operated, when moving to another group, the group Since the waiting time is longer than the change time in the previous group, even if the setting value is changed to the first position of the next group, it will not be missed, and the operability of changing the setting will be extremely good.
